SWITCH.

Application led August 31, 1915.

T0 all whom, t may Concern Be it known that we, EDWARD H. lDAiILKn andMorris L. Sirs CLaiR, citizens ot' the United States, residing` at BonneT erre and Frankclay, in the county of St. Francois and State etMissouri, have invented new and useful limprominente in Switches, ofwhich the following is a specification.

The-present invention relates to improve ients in railway construction.

ln' carrying out'our invention it is our pur` Y pose to provide a switchbetween the main and side lines which shall be operated by mechanismarranged upon an engine to move the switch to, say, openthe same to themain line to close the switch tothe siding, and wherein, after the trainhas passed the switch, will return the same to its initial position.

Ve also aim to provide a switch which is operated by mechanism connectedwith a train with signal device actuated by the bridle rod or an elementconnected with the bridle rod so that the engineer ot' an appreaching`train will be warned or can readily ascertain the position of theswitch, and thus be in a position to operate the switch operatingmechanism if necessary.

It is a further object of the invention to provide switch throwing meanswhich may be automatically actuated by mechanism upon a train or which,lit-desired, may be operated by an approaching train so as not tonecessitate the stopping of the train and the inconvenience ot' one otthe train hands leaving the same to actuate the switch, but which may bealso operated by hand if desired, and further wherein the hand operatingmechanism will not interfere with the automatic or train operatingmechanism.

A further object et the invention is to provide a construction ot thischaracter which shall be extremely simple, easily and quickly applied,cheap to manufacture, and which shall be positive and sure in operation.

lili-th the above and other objects in view, the improvement resides inthe construction, combination and arrangement of parts vset t'crth inthe following specification and talling within the scopeof the appendedclaims.

Referring now to the drawings in detail, the numeral l designates thetracks oi `the main line, and 9; the tracks ci' the siding. 3 designatesthe switch rails which are ar ranged between the main line and siding,and the points ot the switch are connected by the usual bridle rod l.which, in the present instance` has pivotally secured thereto a rodextension 5, and the 'said extension has its end pivotally connectedwith a link G which in turn is pivotally connected with the offset endor foot. 7 ot a target rod 8. The target rod is arranged in suitablebearings provided in a switch stand 9, and the said rodliasits endwhichprojects above the said switch stand provided with the usuallaterally extending different colored plates which form the target 10.vWhen the switch is thrown in one direction, it will be noted that therod 8 will be rotated to bring two of its target arms transversely ofthe track, these arms being each of a similar color, and

also that when the switch is thrown in an opposite direction, the secondpair of target arms will be swung transversely of the track, the saidsecond pair of arms being of a different color from that of the firstmentioned target arm, and so it will, of course, be apparent to theengineer of the locomotive approaching the switch that the said switchis either in an open or a closed position. It is, of course, to beunderstood that if desired, at night a lantern having different coloredbulls eyes may be arranged upon the rod 8 above its target arms and thedilierent eolored lenses of the bulls eyes will serve as an indicatorfor the engineer so that the posi-V tion of the switch may be readilyascertained, this arrangement being common in the art, an illustrationthereof is not deemed necessary.

Positioned at approximately anequal distance from the switch 3 to, saythe outer side of the main line and to the inner side of the switch lineare trip members of aV similar construction, but indicated for distinc-`tion by the numerals 11 and 12, the trip member 11 being for the mainline and the trip member 12 being for the siding. Each of the tripmembers is substantially Y- shaped in elevation and the angularl arms1313 of the said Y-shaped members have upon one of their faces laterallyextending ofi-set portions or flanges 141L The connecting member for theangular portions of the Y-shaped clips have each secured thereto a shaft15, the said shafts extending below the rails of the main line andjournaled in j main track 1.

Pivotally secured, as at 20, to one of the ties which project beyond theinner rail of the main line opposite the switch 3, is a fiat plate 21,the said plate resting upon at least two of the ties.v T he free end ofthe plate is preferably provided with an elongated slot 22 which isarranged concentric of the pivot 20,

' and this end of said plate is preferably covered by a flanged plate orhousing 23, a pin 24 passing through the housing and through the slot 22inthe said plate 21. The plate 2l which, for convenience, willhereinafter be referred to as a rest plate, has arranged upon its upperface adjacent its pivoted end vertically extending stop members 25 and26 respectively, the same being disposed in angular relation to eachother and adapted one to at all times contact with one of the edges ofan arm 27 which is approximately centrally pivoted to the rest plate 21,as indicated by the numeral 28. One' oftheends, which may be termed theinner end of the pivoted arm 27 has connected thereto the offset end ofthe rod 19, and the second end of said arm has loosely arranged thereona link 29, the said link being in turn pivotally secured to the longerarm of an L-shaped lever 30, and this lever is pivotally securedpreferably at the juncture of its angular arms to the rest plate 21, asindicated by the numeral 31. The pivot 31 also serves as a connecting'member for a llat bracket 32, and the said bracket has one of its endsconnected to a link 33 which is pivotally secured to the arm 27 adjacentthe pivotal connection of the rod 19 with the said arm 27,. The bracketmember 32 is approximately centrally connected by the pivot 31 to therest plate 21 and its end, opposite that to which the link 33 isconnectedv` is formed with an upstruck lip 3d. Also the lonOer armof theL-shaped lever 30 has its end formed with an upstruck lip35. The lips 34and 35 have arranged the. aon a longitudinal adjustable member 36 thesaid members 36 being connected with the opposite ends of a helicalspring37. The spring 37 is arranged to normally swing the lipped ends ofthe L-shaped lever 30 and the bracket 32 toward each other for a purposewhich will presently be set forth.

The rod 18, which is connected to the shaft 15 of the trip 11 has itsfree end loosely secured to the L-shaped lever 30 adjacent the pivotalconnection of the link 29 to the said lever.

The shorter arm of the L-shaped lever 30 has pivotiilly secured thereto,as at 39, a

bracket d() which issecured to the extension 5 of the bridle rod fl. 1twill thus be noted that when one of the trip members, say the trip 12,is contacted (in a manner Vpresently to be described) the shaft 15 ofthe said trip will be turned and the rod 18 will be movedlongitudinally, thus swinging the arm 27 upon its pivot 28, andlikewise, through the link connection between the l shaped lever and thesaid arm as well as the link connecticn between the bracket 32 and thesaid arm 2?, both of the rods 18 and 19 will bemoved in unison and theswitch thrown.

It will be noted that when one of the Y- shaped or angular arms ofeither of the trip members contacted to swing the same to a horizontalposition, the second arm of either of the said members will be arrangedin a vertical position, or in a position to be again contacted tooperate the. switch, as will, it

:insana-e is thought, bennderstood. The throwing Vot the switch actuatesthe' target. 10,.but the vsaid target may be movedor swung withoutinterfering with the trip* members, as will 5 hereinafter be more fullyset forth.

Secured to the rest plate 2l `adjacent the non-pivoted or sliding endthereot' is an oti- `:set or angular end fil'of a memberf42, the end ot'said member Vextending approximatelyA centrally over the tie-upon-whichthe switch stand 9 is arranged, but terminating a suitable distance awayfrom said stand, and the free end oi the member Ll2 is termed orotherwise provided with an odset socket i3, through which passes forslidable movement, a substantially rectangular arm il, the said arm allentering the switch stand and being pivotallyv connectedto the oiii'setend 45 of a vertical, shaft-46 which is. ar- .20 `ranged.inloearings inthe switch stand. The

upper end Vof ythe isha ft. e6. liassecured thereto an angular arm 4.7,and .thelsaid arm has .its ifree --end bifureated .and `ipivotally 1secured with-in 'the said biturcatiorn:l ,as aiia.l is lever 49. fLilie.top ot' the 4switch ystand .has a projecting edge `which.y iscurvedyand provided,'adjacent its ends, with .notches 50,either of saidnotches adapted` to receivethe lever 49 afterthe same is employed for 30rotating the shaft i6 and for normally holding the switch either open orclosed to the main line, vshould it be found desirable to operate thesaid switch 'bythe said lever. The numeral 51 designates a second orauxiliary operating lever which is pivoted, adjacent: one of its ends,fas at 52, to the member 42, while its lower end is pivotally connectedto the arm fle. `The switch stand construction permits of the switchbeing 40 actuated by hand. `Theatuiliary `lever 5l being pivoted to thearm 4A awayifrom its pivotal connection 52 with. thexmember lll throughthemedium ot the socket 43 L' permits of the sliding of the said member42 45 when the said lever al is swung in either' direction, suchmovementswinging the rest plate 2l upon its pivot `20.an`d through theconnection between the said rest plate, the bridle rod .-l will swingthel switch points 3, at the same time, ihroughthe mediumiot the link6,. connected with thev otfsetgend of the target rod will simultaneouslyturn the said target rod, consequently turning `the target arms. Theswitch points 3 `may be also directly operated `by the turning of theshaft 46 of theswitch stand through the manipulation of the lever' .49.The lever i-9 is swung in a line with the arm 48 `andis turned upon theswitch stand. The offset end vl5 of the lever 46 influences the arm 4Aand which arm, through fthe medium of its pivotal connection with theauxiliary lever will swing the said leverupon its pivot 52 inthedirection of the memberv 42. .This

. le5 ,provides ari gidcoimetionqbetween:thelever `5l, the arm, iflv andthev'member` e2, causing these `members to movein unison Aandconsequently swing the plate-2l upon its pivot 20land throw Vthe switchpoints 3 `and the target arms i6. .The spring 3'? holds the partsassociated with the rest plate 2l in tion and will be referred. to bylike designat- .lngzcharacters,itis to be stated that the pro- 'ectinocontact-.rod of the l.en ine isada )ted to be extended Sor projectedinthe sideoi` :said .fei'igine from one side 'of lthe engine ufhichfisopposite the sidenpon whichthe .contactrod Vofthe cabooseor end car isprojected, .so that when one oi the trip members contacted by thecontact member of the car, the said trip member will not again becontacted by the member upon the said last car ot' the trai n, but theneXt or second trip member will be actuated by the mentioned contactmember upon the last car to return the same to its initial position.

Arranged within the cab of the locomotive and at a suitable point in thelast car or Caboose, is a lever 55, the same being connected with atransverse shaft 56 which is journaled in suitable bearings 57 upon theunderframe of the vehicle. and the said shaft `has one of its endsprovided with `an otfset `strap or link 6i which has its end secured toa transversely extending Contact member or rod` 62, the said contactmember being journaled in suitable bearings 63 and one of the Abearingsmay have a-closed end or the connection between the .strap andthe saidcontact member may be so arrangel as to engage with one of the bearingstoprevent the lateral `sliding movement oit the contact member62 in onedirection, so that the same will be projected from only one side of thevehicle, for a purpose previously described. The shaft 56 is providedwith an angular extension 6i to which connected a rrod having apivotalconnection with one of the/arms of abell crank lever 66, and tothe second arm of the said bell crank lever is secured a rod 67 that-.isconnected with or. may :form .apart of a ,rod 68,the latter will litidlg@ Y being pivotally connected with a bell crankmembers 01'126, andfrom the foregoing,

when taken in connection with the drawings, the constructioi'i andoperation et the device will, it is thought, be apparent without furtherdetailed description.
